Description

Technical Field

[0001] The utility model relates to the field of contact bridge structures, and particularly to a contact bridge structure with good practicability. Background Technique

[0002] As is well known, the contact bridge structure generally refers to a layout or component arrangement in electronic devices, which is used to connect two or more circuits or systems. This structure is usually used to establish an interface or connection between different functional modules, so as to realize data transmission, signal transmission or energy transmission.

[0003] When the existing contact bridge structure is in use, the structure is single, and the plug and the socket are mostly fixed by friction. When an external force is applied, the plug is easy to break away from the socket, which will make the contact bridge structure unstable in use. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a contact bridge structure with good practicability.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solutions: A contact bridge structure with good practicability, including a plug and a socket. The plug is provided with inserts inserted into the interior of the socket. Two fixing seats are symmetrically arranged on the outer wall of the plug. A first spring is arranged inside the fixing seat. One end of the first spring is provided with a support rod. One end of the support rod is fixedly provided with a limiting plate. A cavity is arranged at the front end of the limiting plate. A second spring is arranged inside the cavity. A clamping block is arranged at the upper end of the second spring. Two positioning grooves are symmetrically arranged on both sides of the socket. A clamping groove is arranged on the inner wall of the positioning groove. The limiting plate is inserted into the interior of the positioning groove. The clamping block cooperates with the clamping groove. A plurality of arc-shaped elastic pieces are fixedly arranged at the upper end of the socket. A push plate is arranged at the upper end of the arc-shaped elastic piece. Push rods penetrating through the clamping groove are arranged at both ends of the push plate.

[0008] Further, in the improvement of the utility model, both the clamping block and the clamping groove are trapezoidal structures.

[0009] To facilitate the operation of the limiting plate, in the improvement of the utility model, anti-slip patterns are arranged on the outer wall of the limiting plate.

[0010] Further, in the improvement of the utility model, the two limiting plates are connected by a U-shaped rod.

[0011] Further, in the improvement of the utility model, an annular groove is arranged on the periphery of the plug, and a sealing ring is arranged inside the annular groove.

[0012] In order to improve the stability of the limit plate when it moves, the improvement of the utility model is that a plurality of stoppers are symmetrically arranged on the limit plate on the outer wall of the plug.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a contact bridge structure with good practicality, which has the following beneficial effects:

[0015] The contact bridge structure with good practicality can move the limit plate to insert one end of the limit plate into the positioning groove. At this time, the first spring will be stretched, and the second spring can provide an elastic force to the card block, so that the card block can enter the card slot. Through the cooperation of the card block and the card slot, the limit plate can be more firmly in the positioning groove. At this time, the limit plate will provide a pulling force to the socket, so that the plug and the socket can be connected more firmly. When the plug or the socket is subjected to external force, the insert on the plug is not easy to detach from the socket, which can improve the stability of the structure when in use.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1-4A contact bridge structure with good practicality comprises a plug 1 and a socket 2, wherein the plug 1 is provided with an insert 3 inserted into the socket 2, two fixing seats 6 are symmetrically arranged on the outer wall of the plug 1, a first spring is arranged inside the fixing seat 6, a support rod 7 is arranged at one end of the first spring, a limiting plate 5 is fixedly arranged at one end of the support rod 7, a cavity is arranged at the front end of the limiting plate 5, a second spring 14 is arranged inside the cavity, a card block 13 is arranged at the upper end of the second spring 14, two positioning grooves 11 are symmetrically arranged on both sides of the socket 2, a card groove 12 is arranged on the inner wall of the positioning groove 11, the limiting plate 5 is inserted into the interior of the positioning groove 11, the card block 13 cooperates with the card groove 12, a plurality of arc-shaped elastic sheets 17 are fixedly arranged on the upper end of the socket 2, and the arc-shaped elastic sheets A push plate 16 is provided at the upper end of 17, and push rods 15 are provided at both ends of the push plate 16 that penetrate the card slot 12. Take the plug 1, at this time the first spring is in a normal state, insert the insert piece 3 into the corresponding hole in the socket 2, and then move the limit plate 5 so that one end of the limit plate 5 is inserted into the positioning groove 11. At this time, the first spring will be stretched, and the second spring 14 can provide an elastic force to the card block 13, so that the card block 13 can enter the card slot 12. Through the cooperation of the card block 13 and the card slot 12, the limit plate 5 can be more firmly in the positioning groove 11. At this time, the limit plate 5 will provide a pulling force to the socket 2, so that the plug 1 and the socket 2 can be more firmly connected. When the plug 1 or the socket 2 is subjected to external force, the insert piece 3 on the plug 1 is not easy to be separated from the socket 2, which can improve the stability of the present structure when in use;

[0023] When the plug 1 needs to be separated from the socket 2, the push plate 16 is pressed to compress the arc-shaped elastic sheet 17. At this time, the push rod 15 will provide a downward force to the block 13, so that the block 13 can compress the second spring 14. At this time, the first spring is reset, so that the plug 1 and the socket 2 can be separated. The structure is simple and the operation is convenient.

[0024] Furthermore, the block 13 and the slot 12 may both be trapezoidal structures.

[0025] In this structure, the outer wall of the limiting plate 5 is provided with anti-slip grooves 8, which can increase the friction coefficient at the limiting plate 5 and make the limiting plate 5 easier to operate.

[0026] Furthermore, the two limit plates 5 are connected by a U-shaped rod 9, which enables the two limit plates 5 to be conveniently operated synchronously.

[0027] Furthermore, an annular groove is provided on the circumference of the plug 1 , and a sealing ring 4 is provided inside the annular groove. When the plug 1 is docked with the socket 2 , the sealing ring 4 will be squeezed to ensure the sealing of the docking point between the plug 1 and the socket 2 .

[0028] The limiting plate 5 lacks a limiting structure on both sides of the plug 1, which will affect the stability of the limiting plate 5 during movement. A plurality of stoppers 10 are symmetrically arranged on the outer wall of the plug 1 with respect to the limiting plate 5, which can provide a limiting structure for the limiting plate 5 on both sides of the plug 1 and improve the stability of the limiting plate 5 during movement.
